- To all whom "it may concern:

The ordinary pocket lighters or ignition appliances with spring lids have the disadvantage that the case of the lights isfirmly connected with the internal parts such, for instance, as the benzi'n container, friction wheel and the means for operating the friction wheel, by soldering, riveting or the like. This circumstance necessitates complicated fitting and also the lighting appliance cannot'be completely put together as a whole before being ground and nickeled, as various parts such as the wick, wadding, friction wheel and ignition pin must not be exposed to the action of the galvanic bath.-

For this reason various operations can only be done after the surface of the case of the appliance has been finished, whereby the surfaces are as a rule damaged and the articles much diminished in value. The arrangement for operating the friction wheel is also more or less complicated in the types of appliances hitherto employed.

Now this invention has for its object to avoid the disadvantages hereinbefore set forth,by the case being made independently, and allthe parts necessary for the lighting (such as the friction wheel, ignition pin,

ratchet wheel and the like) being connected with the benzin container, which forms an independent part. The operation of the triction wheel is effected by means of a springly rack bar connected with the lid, and engaging a ratchet wheel firmly connected with the friction Wheel.

()ne form of construction of the invention is shown as an example in the accompanying drawings,-in which Figure 1 is a side view of the finished lighting appliance with the lid open; and Fig. 2 is a side view of the appliances without the case.

A. supporting frame 6 is fixed ion the benzin container at, in'which frame i) the friction wheel 0 and also a ratchet wheel cl firmly connected with it, are arranged. A

snap spring is fixed on one side of the benzin container at. A rackbar h is pivotally mounted, by means of a pin z, in the lid 9 of the case, and is under the action of a spring which holds the .rackbar in engagement with the ratchet wheel d, the teeth of which slope like those of a saw.

The lighting appliance which contains the wick, wedding, friction wheel, ignition pin and so-forth, and which is constructed complete together withthe benzin container so as to form an independent part, is. simply inserted in the case is and fastened therein by means of the ordinary filling screw Z and a stud m on the snap spring f projecting through an aperture in the case 70. On the insertion of the lighting appliance in the case 70, the spring rackbar it comes into engagement with the ratchet wheel cl, Whereupon the appliance is'ready for use. On the closing of the lid 9 the springy'rackbar h slips along the teeth of the ratchet wheel 03 without actuating it, while on the opening of the lid the ratchet wheel 03 and with it the friction wheel 0 is set in motion.

I declare that what I claim is 1. In a pyrophoric pocket lighting appliance, the combination of a casing, a,

hinged cover for the casing, a benzin container removably mounted within the casing. and provided with a wick, a wheel rotatably mounted on the container, a ratchet wheel connected .to the friction wheel, means for holding a pyrophoric substance in contact with the friction wheel, and a rack bar pivotally connected to said cover for rotating the ratchet wheel only when the cover is opening to throw sparks on the wick, substantially as described.

2. In a pyrophoric pocket lighting appliance, the combination of a casing, a hinged cover for the casing, a benzin container casing, a wick projecting from the container, a friction wheel rotatably mounted on the container, a ratchet wheel connected to the friction wheel, means carried by the conremovably -mounted withinthe tainer for holding a pyrophoric substance in engagement with the friction wheel, a rack bar pivotally connected to the cover, and a spring attached to the cover for pressing the rack bar in engagement with the ratchet- 3. In a pyrophoi'ic pocket lighting zippiiance, the combination of a casing providedwith an an; ening near its top, a hinged cover for the casing, a benzin container adapted tofit within the casing, a snap spring for holding the cover in closed posif'ion, a wick projecting from the container, a friction wheel rofatably container, a ratchet Wheel connected to the friction wheel, means carried by the container for holding a, pyrophorie substance in engagement withthe friction wheel, a rack bar pivotziiiy connected to I spring interposed between the cover and. the

rack bar for pressing the latter in operative 15 engagement with the rmehet Wiiee'i (inning i iiie epening of the cover, substzmfiiuliy as described.
